Re: form submit - nested property problem

[Adam Hardy]

Hi Heather,
it sounds like you are not instantiating any nested beans to store the 
request parameters in. You should do this in your reset method.

I am trying to figure out what happens to the value of my nested checkbox when

I have a bean:

public class FagDTO {

with setter/getter methods for a boolean:

        //for fagtypeform
    public void setEkstraTekst ( boolean ekstra_tekst ){
                logger.info("setting ekstra tekst to " + ekstra_tekst + " for " +
this.getEkskode());
                _ekstra_tekst = ekstra_tekst;
    }
    public boolean getEkstraTekst (){
        return _ekstra_tekst;
    }
I have an ActionForm with setters/getters which return a collection of "Fag"
beans (The above "FagDTO" beans are nested one-to-one in the "Fag" beans. Fag
means "class" in Danish BTW):
public class FagTypeForm extends ActionForm  {

 protected List _fags = new ArrayList();

public void setFags(Fag[] fags) {
                for (int i = 0; i < fags.length; i++) {
                        logger.info("setting fag property " +
fags[i].getFagDetail().getEkstraTekst() + " for fag " +
fags[i].getFagDetail().getNavn());
                        _fags.add(i, fags[i]);
                }
        }
        public void setFags(int n, Fag fag) {
                        logger.info("setting fag at " + n);
                _fags.add(n, fag);
        }
    public List getFags() {
                return _fags;
        }
        public void reset(ActionMapping mapping, HttpServletRequest request) {
        logger.info("calling reset");
	Iterator fagiter = _fags.iterator();
	while (fagiter.hasNext()) {
		Fag myfag = (Fag)fagiter.next();
		FagDTO myfagdetail = myfag.getFagDetail();
		myfagdetail.setEkstraTekst(Boolean.FALSE);
	}		
	resetFields();  
    }
}

Then I have my jsp:

<html:form action="/fagTypeSave">
<!--   cycle over rows of ekskoder -->
  <logic:iterate property="fags" name="fagtypeform" id="fager" indexId="indx"> 
<nested:text indexed="true" name="fager" property="fagDetail.navn" />
<nested:checkbox indexed="true" name="fager" property="fagDetail.ekstraTekst" />
</logic:iterate> 

(submit button stuff...)

</html:form>

My html form gets populated from fagtypeform just fine, and reset seems to
work. But when I change some checkbox values and submit, nothing happens. At
least, the setters/getters of my "FagDTO"
 bean don't get hit and print out logging stuff, like I had hoped. And the
value in my bean doesn't change. 

So my real question is: what is the "property" of nested:checkbox doing? How
can I get nested:checkbox to set the value in my FagDTO when I submit it? 

Thanks,

Heather Buch
